Retirement Benefits [Abstract] |
Pension and Other Retiree Benefits | 6. Pension and Other Retiree Benefits We have a number of pension plans, principally in Germany, the U.K. and the U.S. The plans provide for payment of retirement benefits, primarily commencing between the ages of 60 and 65, and also for payment of certain disability and severance benefits. After meeting certain qualifications, an employee acquires a vested right to future benefits. The benefits payable under the plans are generally determined based on an employee’s length of service and earnings. The majority of these plans have been frozen and are no longer accruing additional service benefits. Cash contributions to the plans are made as necessary to ensure legal funding requirements are satisfied. In the Esselte Acquisition, we acquired numerous pension plans, primarily in Germany (which is frozen to new participants) and the U.K. The Esselte U.K. plan is frozen and was merged into the legacy ACCO U.K. plan in 2019, which was frozen on September 30, 2012. On January 20, 2009, the Company’s Board of Directors approved plan amendments to temporarily freeze our ACCO Brands Corporation Pension Plan for Salaried and Certain Hourly Paid Employees in the U.S. (the "U.S. Salaried Plan") effective March 7, 2009. During the fourth quarter of 2014, the U.S. Salaried Plan became permanently frozen and, as of December 31, 2014, we permanently froze a portion of our U.S. pension plan for certain bargained hourly employees. As of December 31, 2016, all of our Canadian pension plans were frozen. We also provide post-retirement health care and life insurance benefits to certain employees and retirees in the U.S., U.K. and C anada. All but one of these benefit plans is no longer open to new participants. Many employees and retirees outside of the U.S. are covered by government health care programs. Our German Esselte Leitz Pension Plan had an unfunded liability of $167.9 million and $151.5 million for the years ended December 31, 2020 and 2019, respectively. For the ACCO Europe Pension Plan, the Company’s discount rate assumption methodology was based on the yield curve that uses a dataset of bonds with an average AA rating from main ratings agencies. Effective December 31, 2020, we changed our basis to estimate the discount rate assumption to the yield curve that uses a dataset of bonds rated AA by at least one of the main rating agencies, as we determined it better reflects the duration of the plan. The following table sets forth our defined benefit pension and post-retirement plans funded status and the amounts recognized in our Consolidated Balance Sheets:

Pension and post-retirement benefit obligations of $317.1 million as of December 31, 2020, increased from $283.2 million as of December 31, 2019, primarily due to lower discount rate assumptions compared to the prior year. In addition, lower discount rates were the primary reason for the actuarial losses that were recognized in 2020. The accumulated benefit obligation for all pension plans was $962.6 million and $891.3 million at December 31, 2020 and 2019, respectively. The following table sets out information for pension plans with an accumulated benefit obligation in excess of plan assets:

Plan Assets The investment strategy for the Company is to optimize investment returns through a diversified portfolio of investments, taking into consideration underlying plan liabilities and asset volatility. Each plan has a different target asset allocation, which is reviewed periodically and is based on the underlying liability structure. The target asset allocation for our U.S. plan is 64 percent in equity securities, 29 percent in fixed income securities and 7 percent in alternative assets. The target asset allocation for non-U.S. plans is set by the local plan trustees. Our pension plan weighted average asset allocations as of December 31, 2020 and 2019 were as follows:
|  | 2020 |  | 2019
|  | U.S. |  | International |  | U.S. |  | International

The fair value amounts presented in these tables are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the table that presents our defined benefit pension and post-retirement plans funded status. Mutual funds and exchange traded funds: The fair values of mutual fund and common stock fund investments are determined by obtaining quoted prices on nationally recognized securities exchanges (level 1 inputs).

Equity securities and exchange traded funds: The fair values of equity securities are determined by obtaining quoted prices on nationally recognized securities exchanges (level 1 inputs). Debt securities: Fixed income securities, such as corporate and government bonds and other debt securities, consist of index-linked securities. These debt securities are valued using quotes from independent pricing vendors based on recent trading activity and other relevant information, including market interest rate curves, referenced credit spreads, and estimated prepayment rates, where applicable (level 2 inputs). Insurance contracts: Valued at contributions made, plus earnings, less participant withdrawals and administrative expenses, which approximate fair value (level 2 inputs). Multi-strategy hedge funds: The fair values of participation units held in multi-strategy hedge funds are based on their net asset values, as reported by the managers of the funds and are based on the daily closing prices of the underlying investments (level 2 inputs). Real estate: Real estate consists of managed real estate investment trust securities (level 2 inputs). Cash Contributions We contributed $19.5 million to our pension and post-retirement plans in 2020 and expect to contribute approximately $25 million in 2021. The following table presents estimated future benefit payments to participants for the next ten fiscal years:
| Pension |  | Post-retirement
(in millions) | Benefits |  | Benefits
2021 | $ | 41.4 |  |  | $ | 0.5 |
2022 | 41.8 |  |  | 0.4 |

2025 | 43.8 |  |  | 0.4 |
Years 2026 - 2030 | 223.5 |  |  | 1.7 |
We also sponsor a number of defined contribution plans. Contributions are determined under various formulas. Costs related to such plans amounted to $6.8 million, $12.4 million and $13.3 million for the years ended December 31, 2020, 2019, and 2018, respectively. Multi-Employer Pension Plan We are a participant in a multi-employer pension plan. The plan has reported significant underfunded liabilities and declared itself in critical and declining status (red). As a result, the trustees of the plan adopted a rehabilitation plan ("RP") in an effort to forestall insolvency. Our required contributions to this plan could increase due to the shrinking contribution base resulting from the insolvency of or withdrawal of other participating employers, from the inability or the failure of withdrawing participating employers to pay their withdrawal liability, from lower than expected returns on pension fund assets, and from other funding deficiencies. In the event that we withdraw from participation in the plan, we will be required to make withdrawal liability payments for a period of 20 years or longer in certain circumstances. The present value of our withdrawal liability payments would be recorded as an expense in our Consolidated Statements of Income and as a liability on our Consolidated Balance Sheets in the first year of our withdrawal. The most recent Pension Protection Act ("PPA") zone status available in 2020 and 2019 is for the plan’s years ended December 31, 2019, and 2018, respectively.
